针对虚拟现实跟踪技术的快速滤波算法

Tracking Scheme Based on Color Filtering for Virtual Reality

提出一种用于实现手位手形跟踪的颜色滤波方法的计算模型。它可以取代虚拟现实中的数据手套 ,成为人机交互的工具。本方法是基于计算机视觉技术 ,模仿人眼的颜色视觉的特性 ,通过提取手的像素的特征颜色作为参考 ,对整个图像进行颜色滤波处理 ,从而将背景和干扰物体的像滤除 ,只保留手的像。然后经过平滑和轮廓提取处理 ,得到只含有手的轮廓的图像。

An image processing method based on color filtering is proposed to realize hand tracking in a virtual reality system. Based on computer vision techniques, the method simulates the exclusive property of color vision of human eyes. Using the color of hand as a reference, the image received by CCD is processed to eliminate images of the background and other objects. After smoothing and contour extraction, only the profile of the hand is left in the image. The method can effectively eliminate the disturbance of the background and other objects. It can improve the reliability and increase the speed of hand recognition.
